This question tests the ability to spot a word relationship and find the pair that carries the same relationship. The given pair is "Exacerbate : Mitigate". Exacerbate means to make a problem or situation worse, and mitigate means to make it less severe. So the two words are opposites: one makes things worse, the other makes things better. We need a pair of words that has the exact same "worsen : relieve" relationship, in the same order.
Only option (A) keeps both the meaning and the order of the original pair: the first word means to worsen, and the second word means to ease or lessen. So "Aggravate : Alleviate" is the correct match.
Let's summarize:
The correct pair is "Aggravate : Alleviate," which is option (A).
